This is an expansion of the bug reported whereby the variable descriptions were lost on the display.  It appears that if multiple managed scripts are used on a build the 'view selected script' will only show the first script created and not the one you're on.  See attached screen capture - clicked on the link for 'Expose HEAT', but the 'Push Glance' script was displayed ('Push Glance' was the first managed script created, HEAT came later but was inserted as a precondition)
